Have you taken the time to see if this topic is covered in the car Owner’s Manual?
The information on the Tire Rack website is very helpful, but you should be aware that most manuals have a list of “acceptable” tire sizes listed.

Are you considering just a tyre size change or are you considering new wheels and tyres of a different size?
I would strongly suggest sticking with wheels and tyres of a size that are recommended for your car. A responsible place like Tire Rack or a good tyre store can provide you with the acceptable tyre and wheel size combinations that are acceptable.
Note: if you choose a larger wheel with those skinny tyres (Ghetto look) then you are risking wheel damage if you hit a pot hole as the tyres are not tall enough to provide protection to the rim.

On every vehicle sold in the US, there is a sticker ? commonly called the tire placard - that lists the original tire size and the proper pressure for that size. The placard is usually located on a doorpost or in the glove box ? but sometimes it is located in the trunk or on the fuel filler door.

It’s usually best to start with the original tire size and not go searching for other sizes unless you have a problem finding the original size.
